Applicationflled October 26, 1914. Serial No. 868,760.

To all whom it may comema Be it known that we, GUSTAVE KHUMBER andALBERT A. WILLIAMS, citizens of the United States, and residents of thecity andcounty of Denver, State of Colorado, have invented certain newand useful Improvements in Steam-Packing Valves; and we do declare thefollowing to be a full, clear, and exact description of our. invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawing,and to the figures of reference marked thereon, which form a part ofthis specification.

Our invention relates to improvements in steam packing valves, moreespecially for use and application to boilers, and similar steamcontainers, and the invention has for its object the provisionof aconstruction and combination of elements whereby the ordinary leathergaskets and packing of other fibrous nature is obviated, and suchpacking accomplished by the steam expansion.

In the following detail description of our invention, with reference tothe accompanying drawing, many other objects of our invention willbecome apparent.

In the accompanying drawing, Figure 1 is a view of the valve in partiallongitudinal section; and Fig. 2 is a view illustrating a part appliedto the valve for preventing the valve piece from revolving.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingby the same reference characters.

Let the numeral 5 designate a joint of the passage for the steam, thesaid joint having threads 6 in its opposite extremities adapted toengage with threads of the pipes forming the passage. A partition 7 isformed in this joint 5, and is provided with an opening 8 therethrough,adapted to be closed by a valve piece 9, which seats against thepartition 7, the partition 7' having a machined recess adjacent theopening 8 in which the valve piece 9 is received. The valve piece 9 isalso machined to closely fit in the said recess, whereby the valve,

when closed, thoroughly seals the opening I I 9 against the passage offluid therethrough.

A sleeve 10 is threaded in the joint or union 5, as shown at 12, ashoulder 13 being formed on the said sleeve 10, which engages with ashoulder 14 formed on the union 5, making a fluid proof seal at thepoint where the said sleeve 10 is connected with the union 5. A valveoperating'member 15 is revolubly mounted in this sleeve 10, the saidoperating member being provided with an annular flange 17 which overlapsthe extremity of the sleeve 10. The outer-surface of this annular flange17 is of convex contour and machined to closely engage in a concavemachined recess 18 of a coupling collar 19, which coupling collar isthreaded upon the outer extremity of the sleeve 10, and tightly engageswith the outer extremity of the shoulder 16 of the said sleeve 10,forming a tight joint between the coupling collar 19 and the sleeve 10.This shoulder 16 also prevents the coupling collar 19 from being engagedtoo tightly with the flange 17. An operating wheel 21 is connected witha Specification of Letters mane. Patented Mar. 6, 1917.

stem 20, the latter being an extension of the I operating member 15 andreduced in diameter and extending through a housing 22. This housing 22comprises telescoping parts 23 and 24, the part 23 being integrallyformed with the collar 19, while the part 24 is received over the part23. A dowel pin 25 is mounted upon the part 23, and is received in alongitudinal slot 26 of the part 24, thus making the housing 24extensible in a longitudinal'direction, and at the same time preventingthe part 24 from revolving with the turning of the stem 20. A spiralspring 27 surrounds the stem 20, on the interior of the housing 24, thesaid spring being interposed between the coupling collar 19 and the part24 of the housing 22, the part 24 of the housing 22 being engaged with ashoulder 28 of the operating wheel 21. The tension of this sprin 27constantly holds the machined flange 1 in close engagement in the recess18 of the collar 19, thereby preventing leakage of the fluid into thehousing 22.

' The operating member 15 shown in Fig. 1 is provided with alongitudinal hollow 29, in which is arranged threads 30, cotiperatingwith threads 31 formed upon a valve stem 32, which valve stem 32 isreceived in the hollow 29. This valve stem 32 is provided withlongitudinal recesses 40 on opposite sides thereof, which receiveprojections 41 extending into the opening 42 of a plug, or cap 43. Thisplug, or cap 43 is provided with a part 44 which is threaded into theinner extremity of the sleeve 10, the said cap, or plug belng'preventedfrom being unthreaded from said sleeve by means of a screw 45, passedthrough an ear 46 of said" causing the valve piece 9 to seat and unseatitself to open or close the opening-.8, as the case may be.

While we have described and illustrated herein a specific form of ourinvention, it is understood that we are not limited thereto, and thatthe invention may be modified and varied without departing from thespirit of our invention or the scope of the appended claim Having thusdescribed our invention, what We claim and desire to secure by LettersPatent is:

A steam packing valve, comprising a union, a valve seat in said union, asleeve tures inthe presence of two witnesses.
